Abstract: The present invention is a composition of an agent for treating a precursor of a three-dimensional object for removing a support material from a precursor of the three-dimensional object containing a three-dimensional object and the support material, the composition containing water and a water-soluble compound having a solubility parameter (SP value) calculated by using the Fedors' method of 8 (cal/cm3)1/2 to 13 (cal/cm3)1/2. The present invention can provide a composition of an agent for treating a precursor of a three-dimensional object that is capable of removing the support material quickly and a method for manufacturing a three-dimensional object using the composition of an agent for treating a precursor of a three-dimensional object by a fused deposition modeling system.

Abstract: A method for manufacturing a thermoplastic resin composition enabling easy control of the weight average molecular weight of a thermoplastic resin used in a soluble three-dimensional modeling support material, the support material having sufficient strength even when used in the manufacture of a three-dimensional object by an FDM system 3D printer, being less colored with excellent appearance quality, and having a high dissolution speed in neutral water and quickly removable from a precursor of the three-dimensional object without using a strong alkaline aqueous solution; and the thermoplastic resin having dicarboxylic acid monomer units derived from a dicarboxylic acid component and having a proportion of an aromatic dicarboxylic acid monomer unit derived from a sulfonic acid group and/or sulfonate group-containing aromatic dicarboxylic acid component in the dicarboxylic acid monomer units of 10 mol % or more; the method including mixing an organic salt compound represented by formula (I): (R1—SO3−)nXn+  (I).
